Nearly 70 years after it was written, Hitler's best friend August Kubizek's book The Young Hitler I Knew was finally published in English in full:

... it contains, for the first time, the full story of Hitler’s teenage obsession with a pretty girl called Stefanie Isak — whose surname has clear Jewish origins.

And although Hitler’s distinguished biographer Sir Ian Kershaw has rightly dismissed Hitler’s feelings for Stefanie as 'a juvenile infatuation', the passion with which Hitler stalked her and fantasised about kidnapping and committing suicide with her lets us glimpse the mentality of the person he was destined to become.

Furthermore, August Kubizek’s account reveals that Hitler was utterly unconcerned as to whether the girl after whom he lusted was Jewish or not.
